Question

Briefly explain the origin of friction show that in an inclined plane angle of friction is equal to angle of repose​

Answer 1

Answer:

the origin of friction. ... The angle of friction, also sometimes called the angle of repose, is the maximum angle at which a load can rest motionless on an inclined plane due to friction, without sliding down. This angle is equal to the arctangent of the coefficient of static friction μs between the surfaces.
